[USR-TC] Ping timing too high!!

Hello List: TC1000 1-HiPer NMC 2-Hiper ARC 10-Hiper DSP Last night our dial-in was very slow. To pinpoint the problem, I dial-in 3COM and PINGed a server. The response time was around 168MS. Then I PINGed using a LAN. The response time was <1MS. It seems that when users are dial-in (into 3COM) the response time is very high. I think there is something in 3COM causing it. Is there a CACHE built-up in 3COM TR1000? How to find out where is the problem? HELP!!! Kirti
